Description

TECHNICAL FIELD

[0001] The utility model relates to the field of travel equipment, especially to a luggage case. BACKGROUND

[0002] In the field of luggage case design and manufacturing, as a common closure device, the zipper is widely used in various styles and sizes of luggage cases. However, the traditional zipper closure method has some inherent problems in the structural strength and use convenience of the luggage case. Specifically, the zipper located in the middle of the luggage case, due to its relatively soft material, often becomes a weak link in the structure of the luggage case. During use, the main body of the luggage case on both sides is prone to shaking due to external forces, which can cause insufficient strength in the middle of the luggage case, and further cause the engagement part of the zipper to be easily misaligned. Once the zipper engagement is poor, the closure effect of the luggage case will be greatly compromised, and even tearing may occur, causing the entire luggage case to deform or spread apart. This not only affects the durability and service life of the luggage case, but also poses a great safety risk. Especially for luggage cases that can slide while sitting, such as many children's luggage cases, this structure can pose a higher risk.

[0003] To solve the above problems, the existing technology has appeared by setting an opening door structure on one side of the luggage case to replace the traditional symmetrical position zipper closure method. The original intention of this opening door structure design is to enhance the structural strength of the luggage case and avoid the shaking and tearing of the main body of the case due to the weakness of the zipper. However, this design method, while bringing certain advantages, also raises new problems. For special-shaped luggage cases, i.e. non-rectangular or square luggage cases, their opening door structure often follows the conventional rectangular or square design, and the opening of the luggage case often becomes regular and rigid, with a relatively small size. This design not only limits the user's freedom in putting and taking items, making it difficult to put or take some large-sized or irregularly shaped items, but also affects the practicality and convenience of the luggage case. SUMMARY

[0004] The utility model aims at overcoming the above-mentioned defects of the existing luggage case opening door structure, which is regular and rigid, resulting in a small opening size and limiting the user's freedom in putting and taking items, thereby making it inconvenient to put and take items.

[0005] The technical scheme adopted by the utility model is to provide a luggage case, which includes a main body and a sliding mechanism. The sliding mechanism is arranged at the bottom of the main body to support the main body for sliding. At least part of the main body is raised upward to form a convex part. The convex part and the inside of the main body form a unified storage space in communication. An opening is provided on the side of the main body to communicate with the storage space. The opening extends to the convex part and is provided with a side-openable cover plate to close the opening.

[0006] By extending the opening to the protruding part, the side opening of the luggage can be as large as possible along with the protruding part of the luggage, no longer limited to the traditional rectangular or square structure, while ensuring the strength and durability of the luggage, it can significantly increase the opening area of the luggage, making it easier for users to take and put things, especially when large items need to be placed or taken out. In addition, it also makes the shape design of the luggage no longer limited to the traditional rectangular or square structure opening, and can design a more unique and practical luggage.

[0007] Further, the box body has a length L, a width D and a height H, and the protruding part has a length l, a width d and a height h, wherein L:l is between 4:1 and 4:3, D:d is between 1:0.8 and 1:1.2, and H:h is between 5:1 and 1:1.2. By adjusting the size ratio of the protruding part and the box body, the demand of the protruding part as an expanded storage space is met, and the structural strength between the protruding part and the box body is ensured, reducing the risk of deformation or damage due to improper design. At the same time, it can also reduce the impact and vibration of the luggage during transportation, thereby improving the durability and safety of the luggage.

[0008] Further, the protruding part is located on one side of the box body and forms an L-shaped distribution with the box body as a whole, so that the luggage not only has a larger storage space, but also forms a seat part on the non-bulged part of the box body. The length L-l of the non-bulged part of the box body is not less than 10 cm, ensuring that the width of the seat part is sufficient to provide sufficient support and comfort, and the two side edges form an arc transition surface, so that the rider's legs can naturally straddle the two sides, reducing the discomfort caused by sharp corners, and also making the appearance of the luggage more rounded and smooth.

[0009] Further, when the luggage is used as a seat, an arc-shaped concave transition surface is formed at the junction of the box body and the protruding part, and the arc-shaped concave transition surface forms a downward and forward concave space. After sitting down, the body will naturally concave inward, not only providing a more comfortable and fitted sitting experience, but also increasing the contact area between the luggage and the body, thereby improving stability and support, and reducing discomfort caused by luggage shaking or instability.

[0010] Further, the shape of the opening and the cover plate matches the overall shape formed by the box body and the protruding part, not only for providing sealing and security to prevent accidental loss or damage of the articles during transportation, but also to reduce the risk of stress concentration and damage caused by shape mismatch. At the same time, the design of the opening and the cover plate can change with the overall shape of the luggage, so that the opening area of the luggage can be increased, and different shapes and sizes of articles can be taken out and put in more flexibly, improving the practicability of the luggage.

[0011] Further, the area of the opening is not less than 60% of the area of the overall shape formed by the box body and the protruding part, so that the articles are not hindered by the opening and can be easily put in and taken out of various sizes and shapes. The distance between the edge of the cover plate and the outer contour of the overall shape formed by the box body and the protruding part is not more than 15 cm, so that the shape of the cover plate is distributed along the overall shape, ensuring the durability and stability of the luggage under the premise of ensuring the size of the opening.

[0012] Further, the distance between the bottom edge of the cover plate and the outer contour of the bottom of the box body is greater than the distance between the other edges of the cover plate and the other edges of the box body and the edges of the protruding part. When the luggage is placed vertically on the ground and the cover plate is opened, the bottom edge will not contact the ground or other obstacles, avoiding damage to the cover plate or causing inconvenience in using the luggage. The bottom of the box body is also provided with foldable or telescopic footrests. When the user sits on the seat part of the non-protruding part of the box body, the footrests can be unfolded as the support point for both feet, enhancing the functionality and user experience of the luggage.

[0013] Further, the bottom edge or the front side edge of the cover plate is connected to the edge of the opening through a rotating mechanism, which can open the luggage by rotating the cover plate downward or forward. For L-shaped luggage, the rotating mechanism is distributed on the longer side of the cover plate, ensuring the stability of the cover plate opening. The rotating mechanism is provided with a lock device relative to one edge, which can be locked or unlocked with the edge of the opening. When the lock device is unlocked, the cover plate can be rotated downward or forward to open, thereby preventing the luggage from being accidentally opened or stolen, enhancing the safety of the luggage.

[0014] Further, the middle part of the width of the box body and the protruding part is provided with a reinforcing frame distributed along the overall shape formed by the box body and the protruding part. The reinforcing frame is arranged inside the storage space or outside the box body and the protruding part, so that the middle structure of the luggage is more solid, which can significantly improve the overall structural strength of the luggage, effectively resist external pressure, impact and distortion, and prevent the luggage from deforming or damaging during use.

[0015] Further, the left handle foldable or telescopic is additionally arranged on the part of the luggage case corresponding to the convex part, and the right handle foldable or telescopic is additionally arranged on the cover plate corresponding to the left handle, so that the luggage case forms a structure similar to a wooden horse. A person sitting on the non-bulged part of the luggage case body can hold the handle to keep the body balanced, avoiding falling and other safety hazards caused by the shaking or instability of the luggage case, and improving the user experience. The left side cavity is arranged on the luggage case for accommodating the left handle, and the right side cavity is arranged on the cover plate for accommodating the right handle. The left and right handles can be respectively accommodated in the left and right side cavities on the luggage case and the cover plate when not in use, avoiding the problem of occupying additional space by the handle, while keeping the appearance of the luggage case clean and beautiful, making the luggage case more convenient to carry and place.

[0016] Compared with the prior art, the utility model has the advantages that: by designing the convex part and extending the opening to the convex part, the opening area of the luggage case is significantly increased, breaking through the limitation of the traditional rectangular or square opening of the luggage case, so that the user can more conveniently take and place articles, especially large articles. At the same time, by adjusting the size ratio of the convex part and the case body, the demand for expanding the storage space is met, and the structural strength is ensured, reducing the risk of deformation or damage caused by improper design. This design not only improves the durability and safety of the luggage case, but also reduces the impact and vibration during transportation, prolonging the service life of the luggage case. At the same time, the convex part not only increases the storage space, but also forms a seat part for sitting, improving the practicability of the luggage case. The arc transition surface and the concave space further improve the comfort and stability of sitting, providing a more considerate user experience. In addition, the shape of the opening and the cover plate matches the overall shape of the luggage case, reducing the risk of stress concentration and damage, and improving the flexibility of taking and placing articles. The design of the edge of the bottom of the cover plate avoids contact with the ground, protecting the cover plate and keeping the luggage case clean and beautiful. The lock device and the rotating mechanism prevent the luggage case from being accidentally opened or stolen. The reinforcing frame further enhances the overall structural strength of the luggage case, improving the ability to resist external pressure, impact and distortion.

[0017] In addition, the left and right handles and the footrest can enable the user to sit on the non-bulged part of the luggage case body, hold the handles with both hands, and step on the footrest with both feet to keep the body balanced, having a playability while avoiding falling and other safety hazards caused by the shaking or instability of the luggage case. The handles and the footrest can be folded or accommodated when not in use, keeping the appearance of the luggage case clean and beautiful, and facilitating carrying and storage.
